Data Retention Policies for AI-Generated Clinical Notes

Retention requirements aren't one-size-fits-all

AI-generated clinical notes are medical records. Full stop. They carry the same legal retention obligations as any other documentation in a patient's chart - regardless of whether a human or an algorithm wrote them.

But AI transcription introduces a wrinkle that traditional documentation doesn't have: the source audio. When an AI scribe generates a note from a recorded patient encounter, you now have two artifacts - the recording and the transcription. Each may have different retention requirements, and getting this wrong can create both compliance and legal exposure.

Federal and state retention requirements

HIPAA itself doesn't specify how long you must retain medical records. It requires that HIPAA-related documentation (policies, procedures, risk assessments) be retained for six years. But actual medical records? That falls to state law, CMS conditions, and payer requirements.

Here's a general overview of medical record retention periods:

Jurisdiction/Requirement	Adult Records	Minor Records
Most US states	7-10 years from last encounter	Until age of majority + state retention period
Medicare/Medicaid	10 years from date of service	Same
ERISA plans	6 years	Same
California	10 years from last encounter	Until 19 years old or longer
New York	6 years from last entry	Until age 21 or 6 years, whichever is longer
Federal malpractice statute	2-3 years (but discovery rules extend this)	Varies significantly
HIPAA documentation	6 years	6 years

For Canadian providers, retention periods vary by province. Ontario requires 10 years from the last entry or 10 years after the patient's death. Alberta requires at least 10 years. British Columbia and Quebec have similar timeframes.

Keep clinical notes for at least 10 years from the last encounter, or longer if your state or province requires it. For pediatric records, retain until the patient reaches majority plus the standard retention period.

Audio recordings: keep them or delete them?

This is where AI transcription creates a new decision point that traditional documentation never had. You have the original recording. Should you keep it?

Arguments for retaining audio:

• Provides an authoritative source if the transcription accuracy is questioned
• Can resolve disputes about what was said during the encounter
• Useful for quality assurance and provider training
• May be requested during malpractice litigation

Arguments for deleting audio after transcription:

• Reduces data storage and associated costs
• Minimizes the volume of PHI at risk in a breach
• Audio files are large and expensive to store with encryption
• The clinical note is the legal medical record, not the audio

Most practices land on a middle ground: retain audio for a short period (30 to 90 days) to allow for review and correction, then securely delete it. The finalized, provider-reviewed transcription becomes the permanent record.

Whatever you decide, document your audio retention policy clearly. Apply it consistently. And make sure your AI scribe vendor can actually enforce the deletion you specify - not just hide the audio, but cryptographically destroy it.

What your retention policy should cover

A complete data retention policy for AI-generated clinical documentation addresses these elements:

Transcription notes:

• Minimum retention period aligned with state/provincial law
• Where notes are stored (vendor's cloud, your EHR, or both)
• How they're protected during the retention period (encryption, access controls)
• Process for extending retention if litigation or investigation arises (legal hold)

Audio recordings:

• Whether audio is retained at all
• If retained, for how long
• Storage location and encryption requirements
• Secure deletion method and verification

Metadata and logs:

• Audit trail retention (minimum 6 years per HIPAA)
• System logs showing who accessed what and when
• User activity records

Backup copies:

• How long backups are retained
• Whether backups follow the same deletion schedule as primary data
• How backup deletion is verified

Vendor responsibilities vs. your responsibilities

When using a cloud-based AI scribe, data retention becomes a shared responsibility between you and the vendor. Be clear about who owns what:

Your responsibilities:

• Defining retention periods that meet your legal obligations
• Configuring retention settings in the AI scribe platform
• Initiating legal holds when required
• Exporting data to your own systems if you don't want to rely solely on the vendor for long-term storage
• Verifying that deletion actually occurs when requested

Vendor responsibilities:

• Implementing the retention policies you configure
• Executing secure deletion when retention periods expire
• Providing data export capabilities in standard formats
• Issuing destruction certificates upon request
• Maintaining backup deletion aligned with your primary data policies

Put these responsibilities in your BAA. If the BAA is silent on data retention and destruction, you're leaving a significant compliance gap.

Destruction and disposal best practices

When it's time to delete AI-generated clinical notes or audio recordings, half-measures don't count:

• Soft deletion (marking records as inactive but keeping them in the database) is not destruction
• Overwriting storage with random data or using cryptographic erasure (destroying encryption keys) are acceptable methods
• Backup propagation - make sure deletions carry through to all backup copies within a defined timeframe
• Certification - request written confirmation from your vendor that data has been destroyed, including backups
• Retain the destruction record for at least six years, even though the data itself is gone

Test your deletion process. Request destruction of a test record and then verify it cannot be recovered. A vendor that can't demonstrate actual data destruction might not be implementing it properly.
